To all rwhom 'it may camere:

Be it Vknown that I, WILLIAM P. QUEN TELL, a citizen of the United States, residing at New York, in the county oi' New York and State of NewYork, have invented new and useful Improvement-s in Printing- Pressesof which the following is a specification.

This invention relates to' a printingpress adapted' for printing throngh a ribbon and the invent-ion consists in the novel features ofeonstruetion set forth in the following lspeciieation and claims and illustrated in the .annexed drawing in which lFigure 1 is a plan View of a printing press embodying this invention. ifi-g; 2 is a seo- Fig. 3 shows a' View like Fig. 2 with parts in a di'erent Fig. er is areal: 'View of Fig. 3.

Fig. 5 is adetailgperspeetiveView o a paper sto ,f 11h this drawing is showna type holder composed of a. frame or disks `which are Xed or stationary on ast-ationary shaft?) andare adapted -to receive type or type bars c. v A ribbon or yinlrtape o? lies over the type and whenthe platen s presses asheet f to the ribbon on the type an impression ,appears 'on .the sheet. The platen e is carried by-i'raine g retating on a stationary shaft This platen 'frame provided with a gear t engagedby gear h mounted on an arm or frame k and actuated by suitable means 'such as a crankv m; The rotation of the gears will `cause the platen to moveabout the type. The shaft Z2 need not pass entirely .through the type holder @from side toside but might be made integral With or secured to each disk and protrude from the outside of leach disk andorm the means by which the disk is mounted and `fastened to the supporting These protrudingparts would serife as theaxisof the platen frame g,

The paper is fed sheet by sheet onto a guide n pit/oted at 0 and having its free end held toward the type holderby a spring pv which can have its tensionregulated as in dicatedfby screw g. The leading edge of the paper sheet it is slipped onto the guide 'als arrested by neming against .a stop 'r pijvoted at s.

The free or adj aeentend rportions of gtiidef 'n and stop 1' are comb shaped-orv serrated and arranged. so that these serrations lory teeth can between onea'notlier. f

@Vlie-n a sheet has been vplaeed on guide n against stop 9i 'such stop-y is swung so "as toI press or clamp an edge vof the sheet against'- the type holder.- This movement of the stop es is given by a pressing member or actuator 2 secured to the outside of the platen frame' which as the frame moves about the shaft` Wiii engage -a friction roller on thestop" and swing the latter'to the type'holder. 65 A depressing member i carriedl about with the platen engages a fri'etion Vroller 5 'in the .I sheet guide to no'ie'the latter away from# lthe type. The stop thus clamping one edge' of the sheet to the type holder and thej'G sheet guide bein' "eid or swung awayafroin the type holder platen e can 4pass =along.. lhetWeen 'the stopl andv guide to and over the type and press the sheet thereto.

The inkribbon is shown Wou-nd `on spools 75.

The movin-got heavyparts is thusnet *only` avoided but the moving .of entire groupsv oi part-s which have-to perimru'i movements 85 of their lown such as theribbon spool In'ech.-A anisrn and the paper gripping mechanism' is avoided. y

In a slotted' arm or extension '8 of the pieten carrier g is a` bar 9 liavingiingers 10. e0 The bar can be adjusted in the slot toset-the f fingers as requiredf. These ingers'after-,theA platen has.. started printing .andfai'ter the stop fr has freed or unciamped' the; paper come .between the latterand the @type carrier 'and strip orniove the papeijfrtnnl the type..

The stop/r has cuts or'passages. for the strip-H, per fingers to. travel through.y f .1 The stop te can be allowed vtevdrop kclear by its own Weight: to free the sheet or a Mio spring suitably applied tendsto move vvor 'swing the stop from the typeholder.. AA

'are mounted on arms 7 and one of the bobbinsfor if desired bothc'an be releasably held in place by a catch or'hookM which being released will allovsr the spool and ribbon to These spools can'.

bevlifted out of be suitably actuate lace. to. Windv and unwind the ribbon. Into suitable ratchets on .the spools again. These steps ive the reduired prof pellin action to rota e one spool or another, Ba bearings can be applied to make various partsof the 'machine run smoothly but'no. invention is involved in 'such-'feature.

The 'pressure 4of the platen against the type can be regulated by a screw 22. The arms 7 forminga bearing for the ribbon .spools can be. supported or mounted on the hubsor shaftvb.

I claim:-

'1'. A printing press comprising a central shaft witha stationary circular type holder, a platen having its axis of rotation ata practically fixed distance fromfthe center of said shaft with a circular type holder, a rotary frame non-shiftably mounted gon the shaft, and a platen having its axis of rotation Ain the frame at a practically fixed distance from the shaft so vthat the` plat-en can remain in contact with lthe circular type holder dur ing its entire rotation, the exterior of the typeholder being left free or unobstructed.
